Mezger lives on for a bit

[SFO]

from Wolfgang Hatz, Porsche R&D Chief, in coversation with Chris Harris:

"yes, the RSR and Cup will use the old engine. It is very reliable and strong and it does a good job and in the Cup it will be 3.8 litres. It was an easy decision."

[mm450exc]

The only way to go! The Mezger is a fully serviceable racing block - so easy to rebuild vs. changing out the block.

[GT Glee]

Haha excellent!

GT3 roadie will most certainly be 9A1, and guaranteed if PDK.

[OggyDJ]

Really amusing, just re-emphasises what a cracking motor the Mezger was (and still is)

Looks like PDK from the blink-and-you'll-miss-it shots in this:

Sure I saw a 3 pedal set up in that video?

I'm glad it's not just me - I'm sure I saw third pedal, but he clearly clicks up a gear using a paddle

It might be strong and reliable but is it powerful and light enough to compete?

No good being reliable if you are down on power and up on weight.

Pedal box...

[gtphile]

That's a cup car, it has a sequential manual, with clutch pedal, but not used on upshifts with the sequential. They have a power cut which works when you put pressure on the lever.

Aren't they already running minimum weight so the only issue would be can they compete on power with the v8?

Another season win for the Mercedes SLS boys then

It is a 'robotised' clutch (which is completely different from DSG)?

I guess so (the game has moved on). Perhaps is merely for the sake of presence in motorsport

Teaser for the new 991 Cup
It's a Ricardo made sequential with paddle shift operation. Three pedals, nothing like PDK in any way (infact pretty much the complete opposite of a PDK box in every way)
Of course I'm sure the marketing boys will be glad that many will see the paddles and think its PDK.

Details will all be made public at the weekend.

Cups don't have a robotised clutch.
they use a proper sequential so flat up shifts without clutch action using dog gears and an ecu based engine cut.
Clutch is used normally for down shifts and for selecting first gear.
The 997 used a big lever to go up and down, the new car replaces this lever with paddles

Ahh I see. So is more 'robotised lever' because paddles wouldn't offer the amount of force required to shift?

[fioran0]

With paddles it's commonly pnuematic actuation so no "robot" at all.
As you say, having a cable from the paddle would require too much effort.
On the 997 its a cable directly from the gear lever as you have leverage.

The other option would be hydraulic pressure but you wouldn't want that in the cabin. Air is much safer.

Just nomenclature for something not humanly actuated, i.e. your pull of the paddle is not actually shifting the box. Something makes the required effort on your behalf, whether pneumatic, electrical or whatever.
